CORNICE MOLD Application filed October 29, 1927. Serial No. 229,680.

This invention relates to improvements in cornice molds and particularly to mitre molds for plaster cornice work.

The primary object of the invention resides in a cornice mold in which the mitres or corners of a room may be smoothly finished during the molding of the cornice and by the same mold used during the molding operation and without lifting the mold from engagement with the work.

Another object isto provide a mitre mold having a molding edge, the vertical surfaces of which are pointed to provide right angular surfaces one of which lies flat against the wall as the mold is drawn thereacross. while the other is perpendicular to that wall and fits snugly against the adjacent wall as the mold is brought thereagainst after forming the cornice of one wall and by which the cornice on the next adjacent wall may be started without reversing the mold and which assures a smooth and clean oinder between the cornice of two adjacent walls and leaves the cornice smooth and finished.

A further object is to provide a mold of the above kind which embodies a guide mounted thereon for the assistance of a worker in setting the mold on the wall and for securing the necessary guide lines on the ceiling used for guidance when running the mold during the forming of a cornice.

A still further object is to provide a cornice mold which embodies all the features of the present mold with certain added features without materially increasing the cost of the same.

W ith these and other objects in view. the invention resides in certain novel construction and combination and arrangement of parts, the essential features of which are hereinafter fully described, are particularly pointed out in the appended claims. and are illustrated in the accompanying drawing, in which 7 Figure 1 is a perspective view of my improved cornice mold.

Figure 2 is a side elevation of the same.

Figure 3 is a vertical. transverse sectional view on the line 33 of Figure 2.

Figure 4 is a diagrammatic View showing the different positions of the same during the use. of the same.

Figure 5 is a fragmentary horizontal sectional-view on the line 55 of Figure 2.

Figure 6 is an enlarged diagrammatic view showing the angular faces of the cutter edge with respect to two adjacent walls.

Referring more particularly to the drawing, the reference numeral 10 designates my improved mitre cornice mold in its entirety which includes a triangular shape base 11 having two right angularlydisposed edges beyond which spaced guides 12 projectfor engagement with the walls in lieu of the entire edge whereby to decrease'friction therebetween to assure a smooth and easy running. of the mold. Mounted on the base and disposed at an angle of 15 with respect to the side edges thereof is a cutting plate 13, the front of which projects beyond the corner of the base to a plane even with the outer faces of the guides 12; -The cutter plate is made of steel and is riveted or otherwise secured to an aluminum support 14 rising from the base and removably held by an angle strip 15 by bolts 16 while the angle bar. is riveted to the base as clearlV illustrated in Figure 3 of the drawings. The vertical cutting edges of the cutting plates are bevelled. in opposite directions as at 17-, the surfacesof which are disposed at 90 angle with respect to each other. The cutting edge may be of any design and the curves therein. if any. have their relatively vertical portions bevelled the same as the truly vertical edges and which bevels gradually merge into the flat horizontal edges. The purposes of these bevelled edges will be more fully explained hereinafter.

For manually holding the mold. I provide a handle 18 which is constructed of a length of aluminum tubing flattened at its ends and bent to fit flat against the support 14 and the base llrespectivelv. The'handle is disposed rearwardly of the mold so that during the working operation. the cornice formed will not interfere with the hand grip of the user. V

In the use of the mitremold, the operator places the mold against the wall of a wall cornice rod and proceeds to move the same horizontally across the wall from a position between two adjacent Walls. For instance the operator starts at the position indicated at A in Figure 4 and moves the mold from right to left across the wall E to a position marked B 'or until the angular bevelled surfaces on the cutter plate snugly lit and forms the corner in the cornice marked G. Instead of reversing the mold he continues partway across the adjacent wall marked F to the position marked C. The corner G having been formed, the mold is reversed to the position marked D and that wall completed in the same manner and until the final corner of the room marked H has been formed. The angular faces on the cutter plate assure a smooth and finished corner and cornice which may be formed by a single operation of the mold.

Mounted on the top of the supporting plate 7 14 is a mold guide 20 having right angularly bevelled faces 21 and which may be engaged by the ceiling cornice rod, but this is not absolutely necessary. 7 However, these edges may be used for the purpose of markings to receive the guide line.

Fromthe foregoing description, it Will be seen that I have constructed a mitre mold which is capable of performing the functions of the moldsnow in use, in addition to the automatic completion of the corners of a cornice during the running of the mold from one wall to the next adjacent wall. This method will greatly reduce the time for such work and produce a smooth and finished job.

While I have described what I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied without in any way departing from the spirit of my invention, and I therefore do not limit myself to the exact details of construction herein set forth nor to anything less than the whole of my invention limited only by the appended claims.

What is claimed as new is Y 1: In a cornice mold, a base, a molding plate rising from and supported by said base and having vertical and horizontal molding edges, the vertical molding edges being beveIled in opposite directionsat right angles to each other while said horizontaledges are flat.

2. A cornice mold comprising a substantially triangular shape base having two right angularly disposed edges, and a molding plate mounted on said base and extending from the corner of the joinder of said right angularly disposed edges at an angle of approximately 45 with respect to said edges, said molding plate having vertical, horizontal and curved molding edges, the vertical molding edges of said cutting plate being bevelled in opposite directions and curved while the horizontal edges are fiat.

3. In a cornice mold having a molding blade provided with vertical, horizontal and curved molding edges, all of said vertical and curved edges being bevelled at 90 on a horiplontal plane while said horizontal edges are '4. In a cornice mold having a molding ANTONIO K. LAQUIDARA.
